ガスクラスターのイオンビームに対するシンチレーション応答

抄録

  The scintillation response of gas clusters impacted with ion beams was measured to investigate the cluster size effect for scintillation efficiency. The clusters were produced by using a supersonic expansion method, and the average size was determined by the analysis of the Rayleigh scattering light. The scintillation of argon clusters induced by the collision with 3 keV Ar⁺ beam was measured with a photon counting method. It was found that the number of scintillation photons was not proportional to the backing pressure of the cluster source, i.e. the molecular density. The scintillation efficiency increased with an increase in cluster size.
